Washington, March 4 : Paris Hilton's ex beau Benji Madden has slammed reports of his romance with Katy Perry, insisting she is just a beautiful friend.

The Good Charlotte guitarist had raised eyebrows after being spotted canoodling with the `I Kissed A Girl' hitmaker at Sin City hotspot "Wasted Space" at the Hard Rock Hotel & Casino.

But the rocker has now blasted the rumour mill, saying there was nothing but friendship brewing between the two.

"No, it''s not true, we''re friends. She''s beautiful," Fox News quoted him as telling Australia's 2Day FM radio.

"When you''re friends with someone, you don''t want to ever compromise a friendship," he added.

Katy too has previously blasted reports linking her with the vocalist. (ANI)
